To all whom it may concern:

Be it lmoW l-fihat 'I, CARLJP .EDWARDSEN,

a citizen of the United States, residingi at" Stratford, in the countyof Brown and State of South Dakota, have invented certain new and usefulImprovements in Renewal-Points for Worn Plowshares, of which thefollowing is a specification, reference being had to the accompanyingdrawings.

This invention relates to certain improvements in renewal points forworn plowshares and it is an object of the invention to provide a noveland improved point which serves to materially prolong the life of theshare.

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my improved pointwhereby certain important advantages are attained and the device isrendered simpler, less expensive and otherwise 7 more convenient andadvantageous for use,

all as will be hereinafter more fully set forth. a

The novel features of the invention will hereinafter be definitelyclaimed.

In order that my invention maybe the better understood, I will nowproceed to describe the same with reference to the accompanyingdrawings, wherein Figure 1 is a view in bottom-plan of a plow sharehaving a point applied thereto in accordance with an embodiment of myvinvention;

Fig. 2 is a view in elevation at the landside of the plow share asherein embodied.

Fig. 3 is a view in perspective of the point in its initial formation;

Fig. 4: is a view in plan of a blank or bar from which a point may becut; and

Fig. '5 is a bottom plan view of the point after an end portion has beendrawn.

As disclosed in the accompanying drawings, P denotes a plow share ofconventional type including the landside 1.

The body A of the point is welded to the bottom or under face of theshare and is initially substantially diamond-shape in form as indicatedin Fig. 3. By having the body A of this particular configuration it willbe at once self-evident that a plurality of these points may be out froma bar of material without waste.

The body A when initially cut is substan- RENEWAL-POINTronwonnrrowsnhansk.

Specification of Letters Patent; l Patentedtflct. 1; 1918 l W the samethickness at "all points,

and an end portion2 thereof or that portion .in advance of thetransverse dotted liiie a is drawn out to afi'ord a substantially V-shaped extension so as to properly conform to the portion of the plowshare with which it coacts. It has also been found of material advantageto provide the rear portion of the point A at the land side thereof andto one side of the extension 2 with the rearwardly directed heel b' asthe additional metal aiforded thereby materially facilitates the weldingof the point to the land side of the share and which land side alsobecomes worn as well as the point of the share proper. The point isintended to be marketed in this condition and when applied is adapted tobe welded to the plow share with the portion of the point A in advanceof the drawn portion 2, which will be substantially flush with the loweredge of the landside 1, and which results in prolonged life of the shareand causes the same to hold bet- .finally the point is'finished in sucha manner as to cause the same to have the appearance of being integralwith the plow share P. It will also be understood that by drawing outthe forward portion of the body A after said point has been welded tothe plow share, the possibility of burning the point is eliminated, andwhich would be likely to occur if the forward portion of the body A.were drawn out before the point was welded to the share.

From the foregoing description, it is thought to be obvious that renewalpoints for worn plowshares constructed in accordance with my inventionis of an extremely simple and comparatively inexpensive nature and isparticularly 'well adapted for use by reason of the convenience andfacility with which it may be assembled, and it will also be obviousthat my invention is susceptible of some change and modification withoutmaterial departure from the principles and spirit thereof and for thisreason I do not wish tobe understood as limiting myself to the precisearrangement and formation of the inclined and substantially V-shapedextension, the body portion of the point adjacent the land side of theextension being provided With a heel, said point, extension and Intestimony whereof I hereunto aifix my signature in the presence of twoWitnesses.
